Higher levels of air pollution could damage mental health, at least in China Dirty air is dirty air no matter where you are, so, probably not just in China. Image via Pixabay. The findings are based on six years’ worth of mental health outpatient visit data from two major hospitals in Nanjing, China. Nanjing is notorious for its high levels of air pollution, even for China (which has quite a lot of air pollution in general). After comparing the number of visits with records of particulate matter in suspension in the air every day, the authors report that visits were more numerous when air q...

The findings, which were recently published in the journal Environmental Research, stem from nearly six years of outpatient visits data collected at two major hospitals in Nanjing, China — a heavily polluted major city in China. After comparing the numbers with the amount of particulate matter found in the air every day, researchers discovered that visits were generally higher when the air quality was parti...

Rationale Although continuous bag of word (CBOW) embeddings can be trained more quickly than skipgram (SG) embeddings, it is a common belief that SG embeddings tend to perform better in practice. This was observed by the original authors of Word2Vec [1] and also in subsequent work [2]. However, we found that popular implementations of word2vec with negative sampling such as word2vec and gensim do not implement the CBOW update correctly, thus potentially leading to misconceptions about the performance of CBOW embeddings when trained correctly. We release kōan so that others can efficiently t...

Day Around the Bay: 58 San Franciscans Lost Their Lives to Drug Overdoses in November 58 more people died of a drug overdose in the city last month — which now brings the annual total to at least 621 drug-related deaths in San Francisco.
